'Work' in the Bible

If a man therefore purge himself from these, he shall be a vessel unto honour, sanctified, and meet for the master's use, and prepared unto every good work.

But watch thou in all things, endure afflictions, do the work of an evangelist, make full proof of thy ministry.

And the Lord shall deliver me from every evil work, and will preserve me unto his heavenly kingdom: to whom be glory for ever and ever. Amen.
